Everyone is poking fun at 24 for being unrealistic, so let me join in. In the space of 16 hours (8:00 A.M. to midnight), FBI agent Renee Walker has been shot in the neck and buried alive. She has jumped onto a departing tug boat in the dead of night, swum away from a terrorist, and gotten dirty when she clambered ashore. She has cried, or at least been emotionally distraught, several times. But she is fresh as a daisy, right down to her pink lipstick. Her clothes are unsoiled.
